Choice A rationale:

Difficulty sleeping can be an expected finding in a client with adjustment disorder due to the heightened anxiety and stress associated with the condition. Sleep disturbances, including difficulty falling asleep, staying asleep, or experiencing restless sleep, are common manifestations. The psychological distress from the divorce can lead to disruptions in the sleep-wake cycle, impacting overall sleep quality.

Choice B rationale:

Loss of appetite is another potential symptom in clients with adjustment disorder. The emotional turmoil resulting from the divorce can cause a reduced interest in food, leading to appetite changes and subsequent weight loss. This can be attributed to the physiological and psychological impact of stress on the body.

Choice C rationale:

Suicidal ideation is not a common symptom of adjustment disorder. While clients may experience emotional distress and mood disturbances, full-blown suicidal ideation is more often associated with more severe mental health conditions like major depressive disorder or generalized anxiety disorder.

Choice D rationale:

Impaired concentration is an expected symptom in adjustment disorder. The emotional strain and anxiety related to the divorce can lead to difficulty focusing, making decisions, and maintaining attention on tasks. This cognitive impairment is a direct consequence of the psychological distress.

Choice E rationale:

Increased energy is not typically associated with adjustment disorder. Rather, clients with this condition often experience fatigue, decreased energy levels, and a lack of motivation due to the emotional toll of the stressor (in this case, the divorce).
